REVO LVING SPRAYING APPARATUS.

SPECITICATION forming part of Letters. Patent No. 581,416, dated April 27, 1897.

Application filed August 10, 1896.

To all whom/.it may conc-era:

Be it known that we, GEORGE AMBRosE DUNN, a citizen of Canada, and ROBERT States, both residing at Dinuba, county ot' Tulare, State of California, have invented an Improvement in Revolving Spraying Apparatus; and we hereby declarethe following to be a full, clear, and exact description ofthe same.

Our invention relates to an apparatus which is especially designed to travel over the surface of the ground and act as a roller and at the same time to produce a spray of water or other liquid under pressure to be applied either to trees or for use upon roadways and for other similar purposes..

It consists in certain details of construetion which will be more fully explained by which- Figure l is a rear view of our apparatus, sprayer. Fig. 2 is a view showing it as a. sprinkler.

A' is a cylinder which may be made of any suitable materiaL'as boiler iron or steel, and of sullicient strength to resist the internal pressure that may be applied to it. This cylinder has journals or trunnions ll, which turn in a frame O, the frame being preferably any suitable shape for the purpose. ,'lo this frame is connected the usual or ordinary means for drawing or propelling the device over the surface of the land or upon a road, the cylinder rolling upon the surface as it moves. At a suitable point on the 'frame C is journaled a shaft 1),-having a roller E fixed upon it and adapted to roll in contact with the drum or cylinder A.

'F is an air-pump fixed to the frame C, and its plunger is actuated by a connecting rod or pit-man G from the crank-wheel II, which is lixed upon the shaft l); From this pump a pipe I leads into the end of the hollow shaft or trunnion l5 at that side, passing through a suitable stu flin g-box J, which prevents leak- This pipe is of sullicient a second pipe K inside of it, as shown. The pipe K has an angular bend, which allows its lower end to extend down to a point nea-r the bottom of the interior of the cylinder A, where it is provided Serial No. 602,304. (No model.)

with a strainer L. At the opposite end this pipe passes out through the side of the pipe I, with provision for making a tight joint at this point, and thence leads to any desired point of discharge.

If the apparatus is to be used for spraying trees, the pipe may terminate in a hose and nozzle adapted for this purpose, as shown at M. If to be used for street sprinkling, the pipe K is correspondingly bent after emerging from the shaft or trunnions D and carried to the point where it is desired to deliver the water to any of the usual or Well-known\ forms of sprinklers employed for this purpose.

The operation of the device will then be as I follows: rlhe tank A is partially filled with the liquid to be used. If it is to be used for street purposes, it may be ordinary water, and the tank. is provided with a suitable opening, as at O, for refilling when exhausted. If a solution is to be used, as in the case of spraying trees, it will be introduced in the same manner, andthe machine being started the rolling of the drum or cylinder keeps the solution agitated and in proper condition to be applied to the trees. In addition to this the apparatusacts asa roller to crush any clodsand/ to-generall y keep the surface in good sha-pe. The contact-wheel E is kept in rotation by the action of vthe cylinder, and through its shaft D and the crankat -II it actuates the air-pump, thus forcing a supply 0f air through the pipe I into the interior of the cylinder, wliere as much pressure may be accumulated as is desired. This pressure acting upon the surface of the liquid in the cylinder constantly forces it out through the pipe K, when a controlling-cock is opened, and thenceto the nozzle orother discln'trge M. It will be seen that the rotation of the cylinder upon the ground will pr pressure within it to allow it to be stopped whenever a tree is reached and the tree thor oughly sprayed before proceeding. The travel between that andthe next tree will again produce a suilicient pressure Within the cylinder, and thus the work is continued. When used as a street-sprinkler, the airsupply will always besuflieient to keep the proper pressure upon the liquid in the cylinder.
